Marginal product of labor is:the extra output produced by an additional worker, all else unchanged.
  2. 2. the extra wage earned by an additional worker, all else unchanged.the total output produced when an extra worker is hired.the total revenue earned when an extra worker is hired.Question 51. In competitive markets, the elasticity of labor supply is:unrelated to time.inversely proportional to time elapsed since a wage change.unity.directly proportional to time elapsed since a wage change.Question 61. Opportunistic behavior on the part of the employer is possible because:contracts are often incomplete and leave room for implicit understandings between the two parties.employees often reduce their effort level if they are important to the is difficult to monitor all employees and their performances.good quality work can be easily measured.Question 71. Which of the following events will cause a downward movement along the value of marginalproduct of labor curve?An increase in wage rateAn increase in price of the productA decrease in wage rateA decrease in price of the productQuestion 81. _____ represents a firm’s demand curve for labor.The value of marginal productMarginal product
  3. 3. Marginal revenue curveThe horizontal line at the market wage rateQuestion 91. Which of the following will have a downward impact on efficiency wages?Low monitoring costsExcess supply in the labor marketHigh equilibrium wage rateExcess demand in the labor marketQuestion 101. Jason is a salesman who gets 40 percent of the revenue he generates for his company. This is anexample of payment by _____.piece rentfixed salaryexecutive compensationshare contractQuestion 111. In long-term job attachments, a worker’s wage:always exceeds his productivity.always falls below his lower than his productivity at the beginning, then equals it, and then exceeds the higher than his productivity at the beginning, then equals it, and then falls below the same.Question 121. A competitive firm hires workers as long as:marginal product of labor is positive.value of marginal product of labor is positive.marginal product of labor is greater than the wage rate.
  4. 4. value of marginal product of labor is greater than the wage rate.Question 131. Influence cost is a type of _____ incurred while filling positions that have similar responsibilitiesbut carry different pay.deadweight lossopportunity costexternalitysocial costQuestion 141. Assume that a firm is operating in the short run and all resources are fixed except for labor. Thetotal product curve for this firm will increase at a decreasing rate because:value of marginal product of labor is unchanged as more labor is hired.marginal product of labor will decline as more labor is hired.value of marginal product of labor will increase as more labor is hired.marginal product of labor is unchanged as more labor is hired.Question 151. The general health of the population of a country improves as its medical support system improves.Which of the following is a likely outcome of this?Marginal product of labor will increase.Value of marginal product of labor will fall.The equilibrium wage rate will decline.There will be excess supply of labor in the market.Question 162. A risky borrower can pay a lower interest rate if:she invests the amount in a profitable business.she can assure the lender of a low inflation rate.she makes a promise to repay within a short interval.
  5. 5. she can arrange for a collateral.Question 172. Two events A and B in a sample space are considered _____ if the probability that A will happen isthe same regardless of whether or not B has happened.conditionalcorrelatedindependentexclusiveQuestion 182. Which of the following properties can be associated with an indifference curve of a risk-averseinvestor? AnswerIndifference curve for a risk-averse investor is a vertical line parallel to the variance axis.Two indifference curves can intersect at the equilibrium combination of risk and return.An indifference curve closer to the expected return axis gives a better utility than the one farther away.Indifference curve for a risk-averse investor is always downward sloping.Question 192. Refer to Figure 16-1. The conditional probability Pr[A/B] will be:In the figure given below A and B are two sets, such that Pr[A and B]=1/3, Pr[A]=2/4, Pr[B]=3/4.Figure 16-14/9.2/9.4/6.2/6.Question 202.
